Background technology
The YLB-750 type dual-head hydraulic track wrench that Suzhou road cloud mechanical & electronic equipment corporation, Ltd produces is that the construction and maintenance operation of sleeper nut fastener is efficient, and high accuracy is equipped.The machine leads to gasoline engine for power with the import U.S. hundred power.Adopting hydraulic system to carry out drivings and accurately control, is the particularly fit closely construction and maintenance Work machine of High Speed Railway on the new and old line of railway.
Main feature:
1. realize real hydraulic static moment of torsion fastening nut, can the size of step-less adjustment moment of torsion very easily.Torque meter intuitively shows screw-down torque value, accurate, constant output moment of torsion.
2. according to the size of resistive torque, automatically switch and tighten speed, ensure accurately to reach screw-down torque.
3. when carrying out loosening nut operation, without any need for adjustment.
4. the use wearing and tearing of hydraulic spanner mechanical part can not affect hydraulic spanner screw-down torque output accurately and display.
5. spanner is double head type, and efficiency is high, and operation uses and regulate very convenient, lightweight.Expediently, lower railway.
In prior art, the front and back of the both sides of the bottom of dual-head hydraulic track wrench are respectively arranged with monolateral wheel or bilateral wheel; To take turns or bilateral wheel is arranged on bottom frame by monolateral, realize dual-head hydraulic track wrench and carry out in orbit.Monolateral take turns or bilateral wheel carries out in orbit time there is following shortcoming: vertical direction without constraint, the less stable of operation.We have developed a kind of dual-head hydraulic track wrench of the good stability that travels along the railway track for this reason.
Summary of the invention
The present invention seeks to the dual-head hydraulic track wrench that a kind of good stability that travels along the railway track is provided to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution used in the present invention is: a kind of dual-head hydraulic track wrench, comprises body, and the front and back of the left and right sides of the bottom of described body arrange rail clamping travelling wheel respectively symmetrically; Described rail clamping travelling wheel, comprises regulating block, frame installed part, bottom surface road wheel, set lever; Described regulating block is arranged on the middle part of set lever, and is threaded; Described frame installed part is arranged on the bottom of set lever; Described bottom surface road wheel can be rotatably set in the bottom of described frame installed part; There is side linking arm the both sides of described regulating block respectively hinge; There is a lateral connector bar outer end of every root side linking arm respectively hinge; The bottom of described lateral connector bar is provided with side auxiliary wheel; During work, bottom surface road wheel contacts with the upper surface of rail; Described two side auxiliary wheels are separately positioned on the left and right sides of rail.
Preferably, the connecting rod on the road wheel of described bottom surface is connected with the lower thread of set lever through described frame installed part; But described bottom surface its connecting rod of road wheel rotates.
Preferably, described lateral connector bar is provided with tensioning spring respectively and between the sides adjacent of frame installed part.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Dual-head hydraulic track wrench of the present invention, rail clamping travelling wheel on it is provided with the bottom surface road wheel contacted with the upper surface of rail and the side auxiliary wheel contacted with the middle part of the left and right sides of rail respectively, during use and rail be 3 point cantact, realize the locking to rail, the walking of dual-head hydraulic track wrench on rail thus described in this practicality is more stable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Partial sectional view when accompanying drawing 1 is the using state of the rail clamping travelling wheel of dual-head hydraulic track wrench of the present invention;
Wherein: 1, side auxiliary wheel; 2, regulating block; 3, frame installed part; 4, bottom surface road wheel; 5, set lever; 6, side linking arm; 7, lateral connector bar; 8, rail.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1 is dual-head hydraulic track wrench of the present invention, comprises body (not shown), and the front and back of the left and right sides of the bottom of described body arrange rail clamping travelling wheel respectively symmetrically; Described rail clamping travelling wheel, comprises regulating block 2, frame installed part 3, bottom surface road wheel 4, set lever 5; Described regulating block 2 is arranged on the middle part of set lever 5, and is threaded; Described frame installed part 3 is arranged on the bottom of set lever 5; Described bottom surface road wheel 4 can be rotatably set in the bottom of described frame installed part 3; Connecting rod specifically on described bottom surface road wheel 4 is connected with the lower thread of set lever 5 through described frame installed part 3; But its connecting rod of described bottom surface road wheel 4 rotates; There is side linking arm 6 both sides of described regulating block 2 respectively hinge; There is a lateral connector bar 7 outer end of every root side linking arm 6 respectively hinge; The bottom of described lateral connector bar 7 is provided with side auxiliary wheel 1; During work, bottom surface road wheel 4 contacts with the upper surface of rail 8; Described two side auxiliary wheels 1 are separately positioned on the left and right sides of rail.
